Babanalbandi et al.31 have
suggested that H abstraction occurred predominantly from
−CH groups in PLA chains when irradiated by electron beam
to form radical 1, as shown in Scheme 2. In addition, if TAIC
molecules coexisted with PLA, the double bonds of allyl groups
in TAIC were broken to form a pair of radicals shown as 2 in
Scheme 2, with one of them recombined with abstracted H
radical, while the other one combined with radical 1. In this
way, two (or three) allyl groups of TAIC combined with radica
